120 HEMIPTERA-HOMOPTERA. 
A single female specimen. This species bears a considerable affinity to the preceding, 
from which, however, it is very distinct. 
9. Micrutalis lugubrina. 
Acutalis lugubrina, Stal, Kongl. Sv. Vet.-Ak. Handl., Band. iii. Haft. 2 (Bidr. till R. Jan. Hem.- 
Faun. 11.), p. 82 (1860)*. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith); Panama, Volcan de Chiriqui 2500 to

This is a small species, rather larger than the type form of WM. (Acutalis) binaria, 
of a deep shining black colour, except the apex of the tegmina and abdomen, which are 
hyaline; as in M. dinaria the veins are continued further than the dark coriaceous part 
of the tegmina, and on this portion are inconspicuous. The specimens in our collection 
agree so closely with those from Rio Janeiro in the Belgian Museum (from which locality 
Stal described it) that I cannot separate them; there is a slight differeuce in punc- 
tuation, but this is a very variable character in many Homoptera. The species stands 
in the Vienna Museum collection under the name of “ déipartita” (apparently a MS. 
name of Signoret). 
Var. parallela. 
Forma typicali magis parallela, pronoto fortius punctato, humeris minus prominulis, ad medium distinctius 
impresso, et interdum macula flava vel albid& pone medium instructo. 
More parallel than the type form and more strongly punctured, with the shoulders evidently less prominent, 
and with a rather distinct impression in the middle of the pronotum, behind which there is sometimes 
present a yellowish spot. 
Long. 34 millim.; lat. int. hum. 14 millim.

Since writing the above, I have received a representative specimen of M. lugubrina 
from the Stockholm Museum from Dr. Aurivillius; it does not, however, answer to 
Stal’s description, for it has the tegmina entirely hyaline with the veins vitreous, 
whereas Stal says of the species (/. c. p. 32) “tegminibus, parte apicali excepta, 
brunneis, fusco-venosis.” 
10. Micrutalis nigrolineata. 
Acutalis nigrolineata, Stal, Stett. ent. Zeit. 1864, p. 72’. 
Hab. Mexico (Mus. Holm.1; Mus. Vind. Ces.). 
This species is not represented in our collection; it is testaceous, with a dark central 
line running down the pronotum and an abbreviated dark line on each side of it; these 
lines, however, are variable, and there are two specimens from Bogota in the Vienna 
Museum, labelled respectively “ bdiguttata” and “ litterata” (apparently MS. names of 
Signoret), which evidently belong to the same species. Apart from the colour, the
